State of the States -- Population Trends 2010-2017
-- expanding insights through data analytics
-- examining components of change by state

December 2017
.. examining the how, why and where of population change by state from 2010 to 2017.
This section provides an overview of this topic and provides a summary of tools, interactive table and GIS project,
to analyze population change by state by county, using latest
Census Bureau estimates data through 2017.
These data are used by ProximityOne to develop/update annual national state and county demographic-economic projections.
See schedule of related 2018 updates. See more about development of these data/reports below.

State of the States
The State of the States program is broader than the annual population estimates and related components of change data provided via this section.
The broader Windows-based integrated software and database provides access to multi-sourced Federal Statistical System
geostatistical data. These data are mainly state level data, with national summaries, available in a time series structure --
monthly, quarterly and annual refreshes/extensions. Annual series generally start at 2010.
Series include extended annual population estimates (age,race/ethnicity/gender),
ACS annual data,
Personal Income quarterly & annual data,
GDP quarterly & annual data,
REIS annual data,
and other selected Census, BEA, BLS, other agency data resources,

How State & Regional Population is Changing .. go top
Use the interactive table above to view the following narrative describing how the population has changed between 2010 and 2017.

The U.S. population grew by 2.3 million between July 1, 2016, and July 1, 2017,
representing a 0.72 percent increase to 325.7 million.
The population of voting-age residents (adults age 18 and over) grew to 252.1 million (77.4 percent of the 2017 total population),
an increase of 0.93 percent from 2016 (249.5 million).
Net international migration decreased 1.8 percent between 2016 and 2017,
making it the first drop since 2012-2013.
Net international migration continues to be a significant factor
in the population growth of the U.S., adding over 1.1 million people in the last year.

Eight states lost population between July 1, 2016, and July 1, 2017.
Illinois had the largest numeric decline, losing 33,703 people.
Wyoming had the largest percentage decline (1.0 percent).
Three states that had been losing population in the previous year, Pennsylvania, Connecticut and Vermont, saw slight increases.

States in the South and West continued to lead in population growth.
In 2017, 38.0 percent of the nationís population lived in the South and 23.8 percent lived in the West.

Natural Change
Natural change is the difference between births and deaths for an area.
Often natural change is positive which means that there are more births that deaths for a year or period.
This positive natural change is referred to as natural increase. Examples of natural increase exist across the U.S.

The opposite of natural increase, natural decrease, occurs where there are more deaths than births resulting in population decrease. Areas with aging populations often have natural decrease.

Migration
Migration is the movement of people from one area to another. It is often expressed as net migration,
which is the difference between how many people move into and out of an area.
When net migration is positive, a population has more people moving in than out. Migration is split into domestic migration and international migration.

Domestic migration refers to people moving between areas within the U.S., and is often one of the largest contributors to population change.

International migration refers to people moving into and out of the U.S., and
consists of a diverse group of people such as foreign-born immigrants from many countries around the world,
members of the U.S. Armed Forces, and U.S. citizens working abroad.

Adding the net domestic and net international migration yields the net migration.

Components of Change
Analyzing the components of change is an enlightening way to understand how the U.S. population is shifting over time.
Looking at areas across the country, we can identify groups
of areas that grow (or decline) mainly due to migration and others that grow due to natural increase.
